Panic when creating an aws.lb.ListenerRule resource

[aureq]

Describe what happened

This may be related to #3427

I'm creating a simple ALB with a listener rule and the CLI panics with the error shown below.

Sample program

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

const vpc = new aws.ec2.Vpc("main", {cidrBlock: "10.0.0.0/16"});

const subnet = new aws.ec2.Subnet("main", {
    vpcId: vpc.id,
    cidrBlock: "10.0.12.0/24",
    availabilityZone: "ap-southeast-2a"
});

const subnet2 = new aws.ec2.Subnet("subnet2", {
    vpcId: vpc.id,
    cidrBlock: "10.0.5.0/24",
    availabilityZone: "ap-southeast-2b"
});

const secGroup = new aws.ec2.SecurityGroup("allowTls", {
    description: "Allow TLS inbound traffic and all outbound traffic",
    vpcId: vpc.id,
    tags: {
        Name: "allow_tls",
    },
});

const loadbalancer = new aws.lb.LoadBalancer("payload-lb", {
    loadBalancerType: "application",
    securityGroups: [secGroup.id],
    subnets: [subnet.id, subnet2.id],
    internal: true,
});

const targetGroup = new aws.lb.TargetGroup("payload-tg", {
    port: 80,
    protocol: "HTTP",
    targetType: "ip",
    vpcId: vpc.id,
});

const listener = new aws.lb.Listener("my-listener", {
    loadBalancerArn: loadbalancer.arn,
    port: 80,
    defaultActions: [{
        type: "forward",
        targetGroupArn: targetGroup.arn,
    }],
});

const listenerRule = new aws.lb.ListenerRule("my-listener-rule", {
    listenerArn: listener.arn,
    priority: 100,
    actions: [{
        type: "forward",
        targetGroupArn: targetGroup.arn,
    }],
    conditions: [{
        pathPattern: {
            values: ["/path/*"],
        },
    }],
});

[aureq]

Adding more context, only the latest version 6.42.0 is affected by the panic. So #3427 is probably a good candidate.

[flostadler]

In #4083 lb.Listener and alb.Listener were enrolled in PlanResourceChange.
The panic here is seems to be for lb.ListenerRule. My hunch is that this resource (and alb.ListenerRule) needs to be enrolled in PlanResourceChange too.

[Vojtrex]

I've experienced this exact issue. Had to temporarily downgrade the pulumi_aws back to 6.41.0, which does not introduce the panic as @aureq has mentioned.

[flostadler]

@Vojtrex Sorry you're running into this. We're already working on a fix and will try to release it as soon as possible

[flostadler]

We fixed this in #4131. Will kick off a release asap

[aureq]

@Vojtrex we just released 6.42.1. Could you please give it a whirl and confirm it's all good on your end? I'll do the same soon as well.

[aureq]

@Vojtrex Confirmed it's working fine for me, and expect that you shouldn't have any issues either.
